How much should I budget for maintenance annually?
A common rule is 4-8% of vehicle value annually, or $0.05-0.15 per mile. New vehicles under warranty cost less; vehicles over 100,000 miles cost more.

What this calculator does
Regular vehicle maintenance is essential for safety, reliability, and resale value, but costs are often unpredictable. The Car Maintenance Budget Calculator helps you estimate monthly maintenance expenses by breaking down routine services, repair reserves, and other car-related costs.
How it works
The calculator combines multiple maintenance expense categories: scheduled maintenance, a repair reserve fund for unexpected issues, and other recurring expenses. You input your monthly driving distance and costs for each category. Results display as both absolute costs and cost per mile driven.
Formula
Total Monthly Budget = Scheduled Maintenance Cost + Repair Reserve + Other Expenses. Cost per Mile = Total Annual Maintenance ÷ (Monthly Miles × 12). Typical benchmark: maintenance costs 4-8% of vehicle value annually.
Tips for using this calculator
- Follow manufacturer's maintenance schedule precisely—skipping services voids warranties
- Track all maintenance receipts to identify patterns
- Budget higher repair reserves for vehicles over 100,000 miles
- Perform seasonal maintenance checks before winter and summer
- Use genuine parts for warranty work but consider aftermarket for non-critical maintenance
Frequently asked questions
What should be in my repair reserve fund?
The repair reserve covers unexpected issues: brake work, transmission problems, suspension repairs. Set aside $50-150 monthly depending on vehicle age.
Do I still need maintenance if I drive very few miles?
Yes—some maintenance is time-based. Oil degrades over time, batteries age, and tires develop dry rot. Budget for both mileage and calendar intervals.
